ONE-HUNDREDTHS TO J S. HARSl-IMAN FIELD, OHIO.

AND H. E. MURPHY, OF SPRING- VEHICLE-WHEEL.

SPECIFICATION forming part of Letters Patent N 0. 655,949, dated August 14, 1900. Application filed J'anuary8,1900. Serial No. 650. (Homer) To all whom it may concern.-

Be it known that LMARION MILTON BAILEY,

a citizen of the United States,residing at Chil- 1icothe,'in the county of Ross and State of 5 Ohio, have invented certain new and useful Improvements in Vehicle-Wheels, of which the following is a specification, reference being had therein 'to the accompanying drawlngs.

This invention relates to certain new and useful improvements in vehicle-wheels.

The general object of my invention is to provide a construction whereby the hub of the vehicle may be thrown'forward or backward of the wheel-center and has reference to a different form of construction from that embodied in my application executed November 28, 1899, particularly with reference to the construction of an auxiliary hub and the relation of hangers to said hub, such hangers being carried by a primary hub.

My invention also relates to details of construction and arrangement hereinafter apclaims.

like reference-letters indicate corresponding parts, Figure 1 represents a sectional view on the line 00 a: of Fig. 2 looking in the direction of the arrows; Fig, 2, a detail view showing the central portion of a wheel with my improvements applied thereto and also illustrating the operation ofmy improvements, and Fig. 3 a plan View of one of the hangers. In my application executed November 28, 1899, the primary hub carried hangers which fit within rings forming the ends of anauxiliary hub, and the hangers had a bearing against such rings, so as to prevent lateral movement of the primary hub with respect to the wheel proper. In the present application the auxiliary hub is composed of a solid channel-iron, to which the spokes of the wheel proper are attached, while the hangers projecting from the inner hub structure are outside of the auxiliary hub and are mounted on spokes which act as guides to hold the internal or primary hub from lateral displacement, yet which at the same time will perpearing, and particularly pointed out in the mit the hub to partially rotate relatively to the auxiliary hub, as will hereinafter appear.

.The letter A represents ordinary. spokes I .on the interior and concave on its exterior,

as shown at O in Fig. 1. upward from near the edges of this auxiliary The spokes project hub, so that there is ample space between them, in which fits a resilient body D, such body being inserted between the spokes from one side of the wheel in one long piece, after which its ends are brought together and secured in such position in the usual or any suitable manner. In the form illustrated the resilient body is a pneumatic tube.

Within the auxiliary hub B is mounted a primary hub 0, consisting of a hub-sleeve E and annular flanges F, having radial arms G,

which unite at their outer ends with an an nular ring H. Hangers I are pivoted to the radial arms by means of a ball-bearing consisting of a stud-bolt J, formed to constitute a ball-cone K, upon which balls L ride, it being understood that the stud-hole in the radial arms is sufficiently large to accommodate the stud-bolt and balls. Such balls are prevented from escaping by the hanger on one side and by the head of the stud-bolt J on the other side. These hangers extend on the outside of the auxiliary hub B and over the top of the resilient body D and have a bearing thereon, as illustrated in Figs. 1 and 2. The upper or bearing portion of these hangers is extended in a circumferential direction, as illustrated at M. The bearing-surface of these hangers is slightly rounded outward fromthe resilient body, so as to prevent digging into such resilient body when it is brought down upon it by reason of the weight being applied to the primary hub, as will hereinafter appear. each of these hangers has a pair of openings in its outer end, as shown at 0, through which extend a pair of spokes A. These spokes act as guides for the hangers and also prevent It will be observed that any lateral movement of the primary hub, although permitting the hangers to swing more or less in order that the primary hub may partially rotate independently of the auxiliary hub. In order that there may be no rattling between the spokes and hangers, I provide sleeves a, formed of red hematite or other suitable material, which fit snugly within the openings 0 and through which said spokes pass. The axle P extends through the hub-sleeve E and is adapted to carry the weight applied to the wheel, as is usual in this class of vehicle-wheels. Upon the hubsleeve is mounted a sprocket-gear Q, which is adapted to drive the primary hub and through its connection with the auxiliary hub the wheel proper.

I will now refer to the operation of my improvements.

As the weight is applied to the axle the primary hub will have a tendency to drop in a vertical line, and the hangers, particularly those above a horizontal line extending through the center of the wheel,will press into the resilient body,which will act as a cushion for the load. Let it be supposed that the sprocket-wheel is driven by means of an ordinary sprocket-chain. (Not shown.) This will cause the primary hub to rotate, and since such hub is connected with the resilient body mounted upon the auxiliary hub by pivoted hangers such hangers will permit the primary hub to partially rotate before acting to rotate the wheel proper. Such partial rotation of the primary hub will cause the pivotal point a to swing more nearly into line with the center of the wheel and the spokes upon which the hanger, to the left, as indicated in Fig. 2, is slidably mounted. This will tend to lengthen the distance between the bearing M of such hanger and the true wheel-center.

At the same time the pivotal point a is moving into line, as above described, the pivotal point I) will move from its full-line position to its dotted-line position. This movement will shorten the distance between the bearing M of the hanger, to the right, as viewed in Fig. 2, and the true center of the wheel. Consequently the primary hub will be drawn to one side of its true center, as shown at o. Inasmuch as the load is applied to the axle P, such load will be applied to the resilient body, and consequently to the wheel proper, at one side of the true center of said wheel. Thus the wheel will have a tendency to move in the direction of the arrow, as indicated in Fig. 2. Should the sprocket-wheel be rotated in the opposite direction or be retarded, the primary hub will relatively rotate in the opposite direction to the wheel proper. This action will cause the pivotal point a to be moved out of line with such center in the manner just described with regard to the point b, so that the primary hub will be thrown to the opposite side of the wheel-center. This will cause the load to have a retarding effect on the movement of the wheel. Thus with this present construction Iaccomplish the same results as with the device illustrated and described in my application executed November 28, 1899, although the details of construction are unlike those of said application.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a vehicle-wheel, the combination with an auxiliary hub having spokes secured near the outer edges of said hub, of a resilient body mounted between said spokes on said auxiliary hub, a primary hub within said auxiliary hub, hangers connected with said primary hub and extending over the resilient body and on the outside of said auxiliary hub.

2. In a vehicle-wheel, the combination withan auxiliary hub with spokes secured thereto, of a resilient body carried by said auxiliary hgb, aprimary hub within said auxiliary hub carrying pivoted hangers, said hangers adapted to extend over said resilient body and on the outside of said auxiliary hub, all substantially as shown and described.
